hi ive been a member for a little while and got a m1008 about a year ago. im just getting started to hopefully get it running. when i got the truck a lot of stuff was missing like the ip. so last week i finally got a 6.2 in a can from gl. has anyone ever put a ip from a 6.2 from a humvee into a cucv 6.2? i could use any advice i have noticed the intake manifolds are different. also how do i see if the glow plugs are good is there soming to look for if i take them out like a spark plug. one other thing is would the oil filler tube be able to be switched over? thanks
